UIL-BURNER.

Specification ci pplication med September To all whom it may concern.'

Be it known that l. AUGUST H. CAILLOU- y n'rrii, a citizen of the United States, residing at Nashville, in the county of Davidson and State ot' Tennessee, have invented. certain new and useful improvements in Oil-Burners; ,and i do hereby declare the following to be a full, clear, and exact description ofi-the. invention` such' as will enableothers skilled, in the art to which it appertains to make'and use the same.

rlhis invention relates to burners for burningheavy hydrocarbon oil, such as kerosene, and more )articularly to a burner wherein the oil is creed to the burner by air pressure. y

More specifically, the object oit' this invention is to provide a burner-ot this nature which is extremely simple in construction, comprising an outer shell having both ends open, and a circular head or plug inserted in its lower open 'end through which the neck ot the burner coil extends. and which neck has a flexible conduit connected thereto for feeding the oil to the burner coil.

A further object of the invention is to provide a burner coil which has a plurality of openings formed in one side of the same,

and also a plurality of openings formed in thc surface of the uppermost convolution ofthe burner coil.

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more particularly described, illustrated in .the accompanying drawings, and claimed.

In describing the invention in detail, ref* erence will be had to the accompanying drawings wherein like characters designate` like and corresponding parts throughout the several views, and in which:

Figure l is a side elevation ot the improved burner, showing the same connected to the supply tank,

Fig. 2 1s a vertical section through the burner, c Fig. 3 is a horizontal section on the line 3-3 of Fig. 2,

of Fig.

Fig. 4L is a section on the line 4-4 Fig. 5 is a bottom lan' ofthe burner.

Referring to thediawings, l designates A the casing of the learner, which casing or shell is preferably cylindrical in' shape and has both oi its ends open. The lower eind Letters Patent Patented Jl une til;

of the cylindrical casing or shell l of the burner is reinforced, as shown at 2, and a plurality of set screws 3 entend through the reinforced portion 2, at spaced intervals, about the circumference of 'thecylinder and they extend into recesses @i formed in the edge. of a head or closureplate 5', whichiits snugly within the lower end oi the casing l. The head 5 is provided with a plurality of openings 6, which extend therethrough and communicate with the interior ofthe casing` above the head 5.

The head 5 is also provided with an opening 7, through which the neckv 8 of the burner coil 9 extends. The burner coil 9 is formed ol" a coiled pipe, and is; gradually tapered in diameter, as it extends'upvvardly, so that. the uppermost convolution l0 of the coil is smaller in diameter than the vlowerinost convolution 1l, as clearly shown in Fig. 2 of the drawings. The upper innermost convolution 10 is provided with a plurality of spaced` openings l2, which communicate with the interior of the pipe coil 9 and from.

Certain of the convolutions of the coli 9 are provided with openings 13 Yformed Ain the sides thereof, which permit a limited quantity of the fuel to pass therefrom for the purpose of heating the coil 9 and facilitating the action of the same.

The neck 8 of the coil 9 has a coupling member 14 mounted thereon to which a Hexn ible conduit 15 is connected. The flexible conduit or hose l5 is connected' to a pipe it, which extends downwardly within the retaining tank 17., to within a short distance of the inner surface ot the bottom ot the tank, as clearly shown in Fig. l or the drawings. A. valve 18 is positioned in the pipe i6 for controlling the dow of fuel therethrough. A pipe 19 and a pipe 20 communicate with the top of the tank l?, and one ot these pipes is provided tor the inlet ot oil into the tank, while ther other is an air pipe, for conducting air into ythe tank. Valves 2l yare carried by each or" the pipes i9 and 20 tor controlling the passage ot duid there through. it safety valve 22 is carried by the tank 1'? so as to allow the escape ot air, in case the same goes above a predetermined pressure within the tank. il gage 23 is also carried by the tank for determining the pressure therein.

rlFlie hlexible conduit l5 will permit permit ot the egress oit' the fuel there tilt Mld f recente burner structure tobe placed at any desired angle.

In the operation of the improved burner; the fuel is forced from the tank 17 by the air' pressure therein, through the conduit l5 and upwardly into the burner coil 9, and aft/er the fuel has started into the burner coil a piece of ignited waste, or any suitable material, is placed beneath the head 5, so that the flametherefrom will pass upwardly through the openings, andthis flame will y i ite the fuel passing out of the openinvfs and lalso ignite'the fuel passing out of theopenings l2, and start the operation of the burner.

From the foregoing description taken in connection with the accompanying drawings, the advantages of construction and of the method of operation ofthe improved oil burner will be readily apparent to those l skilled in the art to which this invention appertains, and while in the foregoing descrip tion, the principle of the operation of this 'invention has been described, together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.-

What is claimed is:

1. In an oil burner, a cylindrical casing,

a head dctachably carried by one end of said casing, a burner pipe oil positioned Within said casing and having its convolution gradually decreasing in diameter as they extend upwardly, the uppermost convolution of said coil being provided with a plurality of spaced fuel egressing openings,said head provided with a plurality of openings communicating with the interior ot' said casing, and fuel-conducting means connected to said coil.

Q. In an oil burner, a cylindrical casing, a head detachably carried by one end'ofsaid casing, a burner pipe coil positioned within said casing and having its convolutions gradually decreasing in diameter as they extend upwardly, the uppermost convolution of said coil being provided with a plu-
